I'm not the biggest fan of NSFW. I know it exists and all, but I don't always want to see that shit. Once in a while I get around to it and if it's art I go "OH that's cool art!". When I see too many on the other hand it can get quite filthy for me. For some circumstances like characters that were PURPOSELY sexualized such as Lara Croft, Carmeleta Fox from Sly Cooper or some girl from High School DxD, some kind of MLP anthropomorphic whatever-the-fk-they-call-it, or anything that comes to mind first. It varies from person to person, but they all point back to the same thing.
I got nothing against porn, hentai, rule 34, etc. I just want to point that out for anybody that seemed offended. They got a knack for male/female autonomy which for some people is very difficult to do, but sometimes it's just not necessary to see from many eyes.
It's not like I'd know anything. I don't know or care about people's interests in this kind of stuff, but they're not mine.
